<u><em>Answer:</em></u>x = −4 and x = 1
<span>
<u><em>Explanation:</em></u><u>The two formula's given are:</u>
f (x) = -x+0.5 and g (x) = x²+3x-4
By graphing the two in a graphing tool or graph paper we can find the solutions by looking at <u>the points of intersection</u> and taking the x values of those two points of intersection.
<u>Looking at the graph below:</u>
x=-4 and x=1 are the solutions to the problem.</span></span>
A) Vectors are usually given in the form (x , y), therefore the x-component of v is 1.
B) Similarly to point A), the y-component of w is 6
C) the magnitude of the vector v+w is given by:
√[(x₁ + x₂)² + (y₁ + y₂)²] = √[(1 + (-2))² + (-3 + 6)²] = √(1 + 9) =√10
D) Compute -2 · v = (-2·1 , -2·(-3)) = (-2 , 6) = w
Therefore options B) and D) are true.
Answer:
1/300
Step-by-step explanation:
i think
f(x)=3x^2-18x+10
a = 3, b = -18 and c = 10
The vertex of a parabola is in form a(x+d)^2 + e
d = b/2a = -18/2(3) = -18/6 = -3
e = c-b^2/4a = 10 - -18^2/4(3) = 10-27 = -17
Now the vertex form of the parabola becomes 3(x-3)^2 -17
Use the vertex form of the parabola in the vertex form of y = a(x-h)^2 +k
Where a = 3, h = -3 and k = -17
Now you have y = 3(x-(-3))^2 +(-17)
Simplify: y = 3(x+3)^2 -17
The vertex becomes the h and k values of (3,-17)
751.2 divided by 25 is 30.048.
